(Cr s-c5) This invention relates to hemp dressing machines, and has for its object to provide a machine whereby a hemp, such as manila hemp,

may be dressed economically and continuously without need of any skill. I In the accompanyingdrawings:

Fig. 1 is a schematical front view ofamachine embodying the invention.

Fig. 2 is a fragmentary front view of chains for hanging dressed materi V Fig. 3 is an enlarged fragmentary front View of an, arrangement for feeding material shown in the right-hand end in Fig-1. v r

Fig; 4 is a side view of an arrangement of a driving pawl with its associate means for rotating a shaft carrying supporting plates .f orhemp material.

Referring now to the drawings, I represents a frame of the machine, on which a lever 2 is pivotally supported. 4 represents another lever pivotally supported on said frame I, one endof which is pivotally connected with one end of the 5 and 6 represent rollers arranged on the frame I, over which an endless band 7 is arranged. 8 represents aguide roller, which is loosely mounted on a shaft 9 arranged on the frame I, so as to act against the under side of the endless band I. I0 represents an actuating arm securely mounted on one end of the shaft 9, one end of which is connected to the lever 2 by means of a connecting link 3. On the other end.

of the shaft 9, an actuating arm II is securely mounted, which carries. a roller I2 on apin provided on one end, for feeding hemp material. Actuating arms I3 and I3 aresecurelymounted on a shaft I4 supported on the frame. A driving pawl I5 is operatively mounted on and between the actuating arms I3 .and I3 by means of a pivot I5, and is in engagement with a toothed wheel I6 securely mounted on the shaft I4. One end of an extension of the pawl is pivotally connected with one end of a connecting link I 1 which I8 represents a supporting plate for hemp material, a number of which are connected by means of arms I9 at suitable intervals to a revolving shaft I8 supported on the frame. On the shaft I8, a toothed wheel 29 is securely mounted, which is in engagement with the toothed wheel I 6. Beaters 22 and 23 are rotatably mounted on a machine frame 2|, and adjustable pressing members 24 and 25 are provided to co-operate with the beaters 22 and 23 respectively. 26 and 21 represent blades, 26' and 21' their dies, and 28 an endless band arranged over rollers 29, 30 and arranged to the supporting plate I8 -3I An endless band 33 is vertically arranged over rollers32 and 32, and an endless band 31 is arranged over rollers 34, 35 and 36, soas to cooperate with the endless band 28. An endless band 38 is vertically arranged over rollers 39 and 39' so as to co-operate with the endless band 31. Endless chains 40 are arranged over chain wheels 4 I 42 and 43. Cross bars 44 are arranged across the chains at suitable points.

pass between the endless bands 28 45 and 46 represent guide chain wheels, plates for material and 48 a pole for reand 31 41. guide ceivingdressed hemp to be hung thereon (Fig. 1). I In operation, when any one of the supporting plates I8 is horizontally positioned and the roller .terial is pressed against the endless band I by the rollers I2 and 8, hemp material being carried v forwards by co-action of the endless band I and the roller I2. When the lever 2 is moved to a position indicated by the dash and dot line B in Big. 3, as mentioned. above, the bar I! is moved 1 upwards through means of a pivoted lever 4, whereby the driving pawl I5 is brought into disengagement with the toothed wheel I6, so that the supporting plate I8 carrying the hemp materialis maintained in its horizontal position. As

hemp materialis carried forwards, the lever 2 is moved to a. position indicated by the dash and dot line B, whereby the roller I2 is moved to its down position as shown in Fig.1 through means of the link 3, arms I 0 and II. The rear end of hemp material on the roller I2 will be brought downwards with said roller, the rear end of the hemp material which rested on said supporting plate having been removed, as the bar I! is moved downwards through means of the levers 2 and 4, and the toothed wheel I 6 is thereby driven by the pawl I5 to rotate the shaft I8 and hence the material supporting plate I8 through means of the toothed wheel 20 meshing with said toothed wheel I6, and a following next one of the material supporting plates is brought to a horizontal position, on which new hemp material is to be placed, and then the roller I2 will be moved upwards again. In this manner, hemp material is carried The chains are 2 forwards by means of the rollers l2 and 8 and the endless band 1, and in the meantime the pressing member 26 will be moved to its up position and the die 23 will be moved to its down position by suitable means (not shown) and said pressing memher and the die will be at rest in these positions for an interval of time. When the fore end of the material reaches a position somewhat forward from the die 26, the roller 12 will be moved downwards from the feed belt and the pressing member 24 will be moved downwards toward the beater 22, while the die 26' is moving toward the blade, with hemp material resting on it. After an interval of time, the pressing member 24, the

' beater 22, the blade 26 and the die 26 are brought in their respective operative positions, and the rear part of hemp material will be opened by the beater 22. When the fore end of the hemp ma terial reaches a position near the fore blade 21 and the die 2'l' on passing through between the endless bands 28 and 33, the endless band 38 and the die 21 are moving downwards and the pressing member 25 is moving upwards, so as not to interfere with the forward movement of material. In due time, said endless band, die and pressing member will stop, and the fore end of material will advance to a point somewhat forward of the center of the beater 23. At that time, the endless band 38 and the die 21' will be moved upwards and the pressing member 25 will be moved downwards, and when said band 38 is brought in contact with the endless band 31, material will be moved in a reverse direction as will be evident from the fact that belts 28 and 31 being in contact with each other will cause the lower portions of the belts in contact with the material to move in reverse directions with respect to each other. In the meantime, the fore end of material will continue its forward movement, and the length of material between the portion treated with the beater 22 and blade 26 and the untreated portion will reach a position somewhat forward of the center of the beater 23, and the pressing member 25, the blade 21 and die 21 will not be brought in their working positions, although material is moved in the reverse direction, but after an interval of time they will be brought in their working positions, and after said length of material reaches a position somewhat forward of the blade 21 and the die 21' the untreated portion of material will be treated with the fore beater 23 and blade 21. Thus, the treated material is now carried in the reverse direction on passing over the roller 39 of the endless band 38 and by this time the cross bars 44 provided between the chains 40 will come in a position for receiving the treated material between the rollers 35 and 29 by hanging thereon in a doubled or folded position. The treated material hung on said cross bars will be moved with the chains 40 and carried through and between the endless bands 31 and 28, and as soon as the cross bars are moved off the said endless bands, the treated material will hang down and be received on the pole 48. Thereupon completing the hemp dressing. In a short time after the commencement of the reverse movement of material, on the right side the pressing member 24' will be moved upwards and the die 26 will be moved downwards, and accordingly no work will be effected on the right-hand equipment. Thus, the regular operation of the machine is repeated by means of cams, levers and toothed wheels which are arranged in timed relation in a suitable manner.

From the foregoing, it will be seen that the machine according to the invention is arranged to entirely open and dress fibre while in operation when a material is supplied in position on a supporting plate, and accordingly the operation of dressing the material can be done economically and continuously requiring only attendants for supplying material on the supporting plate and for dealing with the dressed material delivered, without need of skill.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I claim:

A hemp dressing machine comprising a material support, an endless feed band mounted near said support, a guide roller mounted on an intermittently oscillatable arm for feeding said material and adapted to be moved into and out of engagement with said endless feed band, two spaced beaters, movable pressing members to co-operate with said beaters, cutting blades and movable dies co-operating therewith for scutching the material passing the beaters, endless intermediate conveying bands arranged one above the other in intermediate spaced relation between said two beaters, endless chains arranged to travel between said intermediary endless bands and in contact therewith and provided with a number of cross bars for carrying material from the machine, and co-operating endless bands arranged tocontact said upper and lower intermediate endless bands respectively, one of said last named endless bands being movable in and out of contact with a corresponding intermediary endless band to intermittently feed the material to the chain conveyer.
